I am supposed to do a communication systems project including MATLAB. Topic maybe something related to for example OFDM system, AMR reading using gprs etc. Or any communication systems related topic. Can some one provide with the brief project description and MATLAB code?

Show that the set {DiracDelta(t-tao): t, tao are real numbers} is a basis set for the analog complex signal space.

Write a new MATLAB function as described in the following:

1. The new function will have three input parameters: f, W, C. 2. Parameter f will specify the frequency of the square wave. 3. The parameter W will specify the width of the single pulse as a number of sample periods. 4. The parameter C will specify the number of square wave cycles. 5. Calculate a number of samples, N, to run the simulation for both waveforms. 6. Create one signal that is a square wave of period 2W samples and lasts for a duration of C cycles. 7. Create a signal beginning with a single pulse of amplitude 1 and a width of W samples followed by N-W samples with amplitude of 0. 8. Plot time and frequency domain plots for each. Use subplots to show all four graphs on the screen at once, arranged the same way as in the reference lecture slide. Scale the plots as necessary so that the desired characteristics can be easily seen. Label the x-axis with the correct units of time/frequency. Run the new function with f=1000, W=20, and C=10.

Make circuit diagrams for each of the objectives:

-tTo observe the input voltage and excitation current waveforms and the hysteresis loop resultingfrom the two waveformsof an unloaded transformer, transformer harmonic components, and tomeasure the power supplied to and power factor of the transformer.

also

-To observe the current waveform and the harmonics of a series lamp-diode circuit, and measure the power supplied to and power factor of the circuit.

Create a specification for a multimeter. This is a technical writing question and must have correct headings and numbering, and must contain proper main heading, an introduction, subsection headings, and proper paragraph numbering.This needs to include: Inputs, Outputs, Functions, Safety

I would like a brief explanation of how to derive the equation for the LM317 voltage regulator as well as how it operates. I am attempting to explain how it works for class tomorrow but dont believe I am correct in my explination.

For a balanced three-phase system, show that the total power is constant. ?

makes it in c++

Kyal is in line at the DMV he has number 325, they are currently serving customer 320.

Use a switch statement to determine which type of loop he needs to use to count to his turn being called.
f = for loop w = while loop d = do-while loop
Output the appropriate loop type from the switch.

Then use any loop type to get from 320 to 325.

Select the appropriate loop type f= for, w =while, d= do-while
[output of appropriate loop type]
320
321
322
323
324
325
It is your turn

the projram starts her..

#include <iostream>
using namespace std;

int main() {

   // Declare appropriate variables
    int number = 320;
   
    //Output the prompt & recieve input
    cout << "Select the apropriate loop type f= for, w =while, d= do-while" << endl;
   
    //Switch to determine & output the appropriate loop type
   
   
    //Loop that goes from 320 to 325 and outputs each number then "It's your turn"
   
   

   return 0;
